Application filed July 3. 1315. Serial No. 107,049.

To all whom it may concern.

Be it known that I, STUART glinnnrnrnn a'citizen of the United States, residing at Stamford, in the county of F airfield. and State of Connecticut, have invented certain new and useful Improvements in interrupters; and I do hereby declare the fob lowing to be a fuili, clear, and exact description of the invention, such as will enabie others skilled in the art to which it appen tains to make and use the same.

This invention relates to new and 'eqefu'i improvements in interrupters and. is par ticularly adapted for use where it is desired to interrupt an electric circuit iii-connection with wireless telegraph apparatus and the like.

Another object oi the invention is to provide a device which may be used in connection with lightin systems in order reduce the consumption of power necessary for illumination.

Another object of the invention is provide a novel means for 'i'ormin the cents between the various moving parts in order to reduce arcing to a'ininiinuni- A still further object or" the invention is to provide a device which may be used run in oil or in connection with a condenser in order that any tendency to will be avoided.

With these and other objects in view; the invention consists in the novei combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawingin which Figure l is a side view in elevation of an interrupter constructed in accordance with this invention showing a portioi'i thereof in section to more clearly illustrate the detailsof construction, and

F ig. 2 isan enlarged detail View of the lateral contact. I

Referring to the drawing the numeral 1 designates the base of the device provided with a suitable standard. 2 having a shaft 3 journaled in its upper end. A disk i of insulating material is mounted. on said shaft and is surrounded on its periphery by a ring;- 5-of a suitable conducive material provided with a plurality of redial extensions 6 between which are mounted the insulating plates 7. The shaft 3 is adapted to be driven by a motor or any other suitable operating element in order to rapidly rotate the disk when the device is in operation.

-.in the plunger 11 which is provide sic-eve is directed toward the PBl'lDliQFy 0;.

the rotating element and has inonntec the axial recess 12 in its outer end the contact roiier 13 is mounted. is journaled on a suitable shaft 14; ranged to run against th periphery o. rotating eienient hereinbefore dos sure of the sleeve 9 and the inner ter 11 of the plunger 11 in order to urge the 1! ii 13 outwardly and into contact with the rotating element. In order to,,insure a nroner contact of theiroller with the sleeve 1 suitable brush 16 is mounted on the v. and bears on the roller as cleariy shown, I the drawing and in order to insure a proper contact between the sleeve and the plunger :1 wire 1? is soidered to the inner i or p uger and to the end closure o its shown in the drake .g it a i stood a suitable insnlatin interposed between the pedesitl sleeve 9 so as to avoid charging the f and case. in order to convey current to the the ineciznnisz'n-hest illustratorin i n'ovided and consi s or :1 pair of which project upwi'irdl from the be 7 have pivotally mounted tierebetween as 20 the upstanding arms 21. pair of intoally extending fingers project outwsrdiy from one side of the arm and jonrnnled Letween the fingers is a shaft 23 on which the :ontact roller is mounted. This conta roller is adapted to engage the side face oi the ring 5 in order to insure a continuous fiow of current into the ring. in order to hold the roller 2% in contact *ith the a compression coil spring connected the base and to the arm 21 and it i seen that the arm will be'nrged tower rotating element as will be clearly i reference to the drawing. Mounted in i base is a suitable bindingpost which connected to a wire 27 which in turn is dered or otherwise electrically connected the standard or arm 21 and will thus b seen that the arm will he in electricui coin- MEG in use it vill be hpparent ironithe foregoing that the shaft 3 isrotated and the tar tation of said shaft willcause the disk 4 to rotate thus causing the wheel 13 to alternately engage the contacting and insulating portions of the ring 5. Such action will cause the current passing from the binding post 26 into the binding post 10 to be rapidlyinterrupted and it will be evident that the frequency may be varied according to the speed of rotation and also according to the number of insulating plates 7 which are inserted in the periphery of the ring. It will also be evident that the roller'Qet will be in contact with the ring 5 at all times and the arc tendency of thedevice will be greatly reduced'owing to the rolling contact.

\Vhile in 'the foregoing there has been shown and described the preferred embodiment ofthis invention, it is to be understood that suchchanges may be made in the combination and arrangement of parts as will fall within the spirit and scope of the appended claims. g What is claimed is z 1. In an interrupter, a base, a rotary disk rotata'bly mounted on the base and provided on its periphery with a plurality of alternate insulating and conductive plates, said plates being connected at their ends by a continuous ring, a sleeve mounted on the base, a rolling contact in one end of the sleeve for engagement with the periphery of the disk, spring means for urging said contact toward the disk to hold the peripheries thereof in continuous engagement, a rolling contact for engagement with the ring, and springmeans for urging the last named rolling contact toward the disk, and binding posts connected to both of the contacts as and for the purpose specified.

'2. In an interrupter a base, a disk rotatably mounted on one face of the base, and provided on its periphery with a plurality of alternating insulating and conductive plates, said plates being connected at their inner ends by a continuous ring, a sleeve mounted upon said base and having one end closed and its other open end in close proximity to the periphery of the disk, a rolling contact member rotatably mounted in the open end of the disk, its periphery adapted to have engagement with the periphery of the disk, spring means for urging said contact toward the disk to hold the peripheries thereof in continuous engagement, a rolling contact for engagement with the ring, spring means for urging the last named rolling contact toward the disk, and binding posts carried by the sleeve and base, said binding posts being connected to both of the contacts.

3. In an interrupter, standards mounted upon one face of the base, a disk rotatably mounted on the standards, said disk provided on its periphery with an alternating conductive and insulating plate, a pedestal on the base, a sleeve mounted on the pedestal, said sleeve having one end opened and its opposite end closed, a rolling contact rotatably mounted in the opened end of the sleeve and adapted for engagement with the periphery of the disk, a ring connecting the inner ends of the conductive plates together, pivoted arms mounted beside the rotating disk, outwardly extending fingers formed on said arms, a polling contact rotatably mounted between the fingers, said contact being adapted to engage the rlng of the disk, and spring means to urge said contact toward said disk to hold the rolling contact in en gagement with the rings.

In testimony whereof I ailix my signature in presence of two witnesses.
